Applied Geochemistry

Published: 7 March 2011

Applied Geochemistry includes geochemical studies of how the elements moving or fixed in the environment depends on the physicochemical environmental factors, and has a particular focus on methods to prevent and reduce the environmental impact of mining.

Basic research is combined with applied resource-oriented research. Methods and knowledge developed in the basic research are used in applied projects.

An understanding of how the elements are mobilised or fixed in the environment depending on physiochemical factors is the basis for understanding the state of the environment, and this is environmental geochemistry. The basic research at Applied Geology aims at understanding natural concentration levels and mobility of the elements under natural conditions.

The applied research in environmental geochemistry includes studies of pollution from anthropogenic activities and methods to decrease and prevent pollution. At Applied Geology the most important research fields are to develop methods for remediation of mine waste and to decrease the release of nitrogen from active mines.

Research in environmental geochemistry demands good analytical methods. Together with the company ALS in Luleå,  research in development of analytical methods by using ICP is performed. The aim is to develop improved methods for analysis of concentrations of elements. Stable isotopes of metals and metalloids are studied by using MC-ICP-MS.
